XR 500 Constant Disconnect/Reconnect iPhone XS (and haywire logs)

[digruski]

So my network is this:

ISP Modem(Wifi Disabled) -> XR500(Router Mode):

Vivint Panel

HP OfficeJet

Amazon Firestick x2

Apple TV

Xbox One

iPhone XS (the offender)

+/- 2 other iPhones at any time. 

My primary issue is that my iPhone XS seems to get booted from the network constantly. Every time I wake up the phone I have to manually reset the connection or wait a minute or so. I have tried replacing the phone, disabling smart connect,  manually choosing the 5G network. My PC is hardwired to the ISP modem, but if I disable ethernet and switch to wifi the XR500 doesnt like my PC either.

When I looked at the logs its a bunch of this:

[WLAN access rejected: incorrect security] from MAC address 8c:57:9b:e7:30:7b, Thursday, December 26, 2019 19:17:56

[DoS Attack: RST Scan] from source: 13.249.56.101, port 443, Thursday, December 26, 2019 19:14:35

All the IP's are registered to Facebook and Amazon and there is no device with that MAC address on my network.

Not sure what the next step is at this point.

That MAC address is from a device created by the Wistron Neweb Corporation, this could be a Sky Box for example if you're in the UK. I would suggest on the devices you're having trouble on that you 'forget' the WiFi network completely on each device and then reconnect by retyping the password in and see if that resolves it.
